This response header is set to its default quite early in
the request/response process, so you just need to find a
point at which to change it. You can do that in each page
handler, of course, but that gets tedious. CherryPy 3 has a
response_headers Tool that you can easily turn on in config:

    tools.response_headers.on = True
    tools.response_headers.headers = [('Server', 'my-web-app
name/ver')]

For CherryPy 2, you should be able to write a similar
filter.

Indeed, CherryPy already has such a filter:
